Abstract
A method and apparatus for joining a user to a call in a group communication network provides for receiving an indication from a user who wishes to initiate a group call and sending a request to a server to add the user to the group call if the group call is in progress. The method and apparatus also provides for announcing the group call to the user, receiving acknowledgement from the user who wishes to participate in the announced group call, and forwarding media to the user after its traffic channel is re-established. The method and apparatus also provides for a significant reduction in the actual total dormancy wakeup time and latency by exchanging group call signaling even when mobiles are dormant and no traffic channel is active.
